While the exact source code is not explicitly documented as a standalone academic paper, the plugin operates on principles common in dereverberation:
| Parameter | Best for | Artifacts possible | |-----------|----------|--------------------| | Small room, Amount 6-12 dB | Podcasts, voiceover | Chattering, metallic sound | | Large room, Amount 3-6 dB | Live music recording | Hollowing, loss of ambiance | | High sensitivity | Dialogue with dynamic range | Over-suppression of trailing consonants | audacity dereverb plugin
| Plugin | Quality | CPU Usage | Artifacts | |--------|---------|-----------|-----------| | Audacity Dereverb (built-in) | Moderate | Very low | Metallic resonance, warbling | | iZotope RX De-reverb | High | High | Minimal | | Acon Digital DeVerberate | High | Medium | Low | | Spleeter / Open-Unmix (AI-based) | High (for voice) | Very high | Transient smearing | While the exact source code is not explicitly
Using the DeReverb plugin in Audacity is straightforward. Here's a step-by-step guide: For users of the open-source audio editor Audacity,
